After a nearly fatal accident, 21-year-old Lamb Mannerheim (Julianne Hough) is beginning to realize that the world is much bigger than her small, God-fearing Montana town. Armed with a big, fat insurance payout and a checklist of untried sins, there’s only one place for her first taste of temptation…Las Vegas! And, with the help of a few new friends (Russell Brand and Octavia Spencer), Lamb embarks on an oddball odyssey of lost souls, broken faith and cheap cocktails…a true journey of the heart.
